3-phase built-in filter for machine applications

Pinterest LinkedIn Tumblr

SCHURTER is expanding the successful 3-phase filter families FMBC EP and FMBD EP with new variants for machine applications. The new filters meet the requirements of machine safety according to IEC 60204-1. They are suitable for 3-phase or 3-phase with neutral conductor applications with rated currents from 16 to 230 A.

The two-stage built-in filters FMBC EP and FMBD EP have a particularly compact design with a small footprint and high performance at the same time. They are suitable for industrial or energy applications such as EV fast charging stations or battery storage.

IEC 60204-1: Machine safety

Every machine or system that wants to be placed on the market in the EU and associated countries must bear a CE mark issued by the manufacturer himself. With this label, the manufacturer guarantees that its product meets all applicable legal and technical requirements.

In Europe, the Machinery Directive 2006/42/EG and the Low Voltage Directive 2014/35/EU define minimum standards with regard to safety and occupational health and safety requirements. The implementation details are defined in separate specifications, the so-called harmonizing standards. One of these harmonizing standards is IEC 60204-1. It applies to electrical, electronic and programmable electronic equipment as well as to groups of networked machines, including switch cabinet construction.

New filter variants

The new filter variants meet the requirements of this standard IEC 60204-1. The filters have a short discharge time of the capacitors, so they have a touchable residual voltage of <60 V in 1 or max. 2 seconds after disconnecting the voltage. Furthermore, the insulation value between phases and earth is at least 1 MΩ thanks to larger resistances. The filters are designed for currents from 16 to 230 A at an ambient temperature of 50 °C.

All family members are ENEC and cURus approved and recommended for applications up to 760 VAC. The standard variants are designed for industrial applications with leakage currents <10 mA. Special versions with leakage currents <3 mA are available for applications that are particularly critical of leakage currents.
